LEGO GBC 8


1. Building instructions

Download here the building instructions for LEGO GBC 8:

To open the building instructions you need to download and install LEGO Digital Designer.

NOTE 1: The GBC should work properly but it needs a little bit of fine tuning by yourself. If you are experiencing                         difficulties here, feel free to ask;)

NOTE 2: Use the XML file to upload the partlist of LEGO GBC 8 to your Bricklink Wanted List. Open with Notepad
and copy/paste the text to Bricklink.

NOTE 3: You may not download and reupload the building instructions without my permission. Just ask first;)

4. Review

See Geek.com for the original article.

This is not GBC builder Philip Verbeek’s first outing with the concept — he’s on his 8th GBC build. Some of the past ones have included ball launchers, ramps, elevators, grabbing claws, and more. This time Verbeek has gone for a very ambitious build consisting of elevators, moving ramps, and a crazy undulating bridge. He’s also incorporated Lego NXT that allows him to track data about system performance and control the whole thing with an Android app.

This new GBC consists of about 2,000 pieces, which is fewer than some previous builds. The contraption is powered by 2 XL Legomotors — one for all the modules, and one for the airpump. The mechanical energy from the motor is transmitted to most of the modules via gears or a network of strings woven through the blocks.

Possibly the coolest aspect of this GBC is the Sinusoid ramp at the beginning. Watching it undulate while suspended by a network of strings its kind of mind boggling. It must have taken a good long time to get it timed correctly.

Verbeek has also been kind enough to give us a walkthrough of the design. You can follow along with the gallery above to see each module up close.

  • Stop-go mechanism 1: Stops balls and let them go by at the right time.
  • Sinusoid: Moves the balls by making a sinusoid motion.
  • Stop-go mechanism 2: Stops balls and let them go by at the right time.
  • Elevator: Lifts the balls to a higher level. Every time 3 balls can fit in the cabin.
  • Bridge: Leads the balls of yellow tower to the blue tower. When the elevator is down the bridge will go up and when the elevator is up the bridge is down.
  • Stop-go mechanism 3: Stops balls and let them go by at the right time.
  • Vertical pushers: Pushes the balls in a vertical way up.
  • Color sensor: takes measurements of the balls.
  • Ball pump: Pumps every time one ball. A new ball takes a place beneath another ball and then pushes them up.
  • Android app: Controls the LEGO GBC.

If you think you have the time and patience to assemble your own GBC with near-clockwork precision, Verbeek has made the plans available to download. It’s also on Lego’s Cuusoo page, if you think it’s worth supporting.

Maybe Lego will finally make one of the GBCs a reality? You can also track Verbeek’s projects on Facebook and his YouTube channel.

 

5. Music

This time I used the soundtrack from the movie “Madagascar 2 Escape Africa” called “Once upen a time in Africa” and I used the soundtrack from the movie “The Road To El Dorado” called “Wonders of the new world”. I created the soundtrack of GBC 8 by mixing these two soundtracks together.

The Road To El Dorado – Wonders of the new world

    Hi PV-Productions and GWorks,

    Hey Philip, I’m attempting to build your GBC 8 using GWorks instructions (thanks, GWorks, they were awesome!). I’m having difficulty with the tall blue tower. As I turn on the motor, the balls somewhat go into the tower, but mostly are forced back out the opening. I’ve noticed on your youtube video that your balls stay put in the tower for a second, and then move up for a second. My balls instead stay put, and then do a quick drop. Any advice on how to calibrate this?

    How do we get the 2172 pieces to make this thing?

      Hi John,

      If you already have a LEGO collection then you can use these ofcourse. For specific parts you can shop at http://www.bricklink.com/ to get these.
      However, you can also replace some parts which I used or maybe make a whole new construction to get the same job done.

      Hope that helped

    Hi Philip,

    Amazing model! Well done and kudos for publishing the instructions online.

    Do you have a part-list for bricklink? I’m thinking of bricklinking most of the parts so my son doesn’t get upset with me using his LEGO!

    Cheers

      Hi Steve,

      I have converted the LDD file to a XML file which you can import to Bricklink. See above. Unfortunately some parts are not available on Bricklink. However, maybe you don’t need these parts because you already have them or because I recreated parts which are not available in LDD, for example the pneumatic pump.

      Summarizing: Take a close look before you order anything on Bricklink!

      Hope that helped.

      Gr. Philip
